Promptblock – detect prompt injections in GitHub issues

I recently made promptblock! I maintain a few small OSS repos and will frequently triage + examine issues filed by users with Claude. This helps me feed public github issues into automated systems with confidence, by merely gating these systems with deterministic checks for promptblocks thumbs up emoji.

It's not perfect, but curious to know if people find this useful!
